Diane Morse was a 40-year-old teacher at the Ardmore Child Care Center, which operated out of a wing of Lower Merion High School. On July 28, 1994, an unlocked rear entrance that contractors had been using allowed Arcelia Truman Trudy Stovall to enter the building. Stovall went to Morse’s classroom during lunchtime and opened fire, killing Morse in front of children who were mid-meal; the children were physically unharmed.

Police arrested Stovall at her home shortly after the shooting and she confessed, later facing murder and related charges. Court documents state Stovall was convicted of Morse’s murder and incarcerated in a psychiatric hospital; other reporting says she pleaded guilty to first-degree murder and received a life sentence. Morse’s family pursued civil claims about how an intruder accessed the childcare classroom through an unsecured door amid construction.

Does anyone have details about the school’s security procedures or the contractor access arrangements at the time?
